Code:

> x1=1234.20
> echo $x1
1234.20
> echo $(printf "%.4f" "$x1")
1234.2000

something else to think about

Code:

> x2=1234.2000
> x3=$(echo "$x1"-"$x2" | bc)
> echo $x3
0

Perhaps one of these approaches will help you.

Force awk to compare the string numerically...

Code:

echo 1234.2000 | awk '{print $0+0}'
1234.2
echo 1234.20 | awk '{print $0+0}'
1234.2
